Hi Dave, Thank you for your reply.It means a lot to me. By the way, is it possible to have the analysed data on the study you mentioned regarding the solderability "conditioning " ? Can we establish the correlation of solder shelf life based on y

DC powered Power-up and ageing burn-in equipment, preferably non-product specific, starting from room temperature down to -41 degrees celcius and up to +71 celcius at a rate of 7 celcius per minute. But anyone who could suggest a manufacturer would b

Chip Cap Specs

Can someone explain what ageing means in terms of chip caps. Capacitor vendors state 7% per decade hour or 2-5-1 per decade hour. What does this mean? I think capacitor values lower over time but what is a decade hour. Thanks, Chris

Interesting. I'd start with the "Help Desk" at the Reliability Analysis Center [http://rac.iitri.org/]. Please get back with your findings.

Tantalum caps degrade over time. You should not be seeing "chipped-off & cracks" regardless of the age. This should not be a shelf-life issue, unless you are storing them in an aquarium. Tell us the story. Solderability is a shelf-life issue and

Question on Nitrogen Consumption during Reflow

It's possible that N2 vogued at the dawn of the NC age. Once practitioners jiggered their profiles and more importantly, paste suppliers developed a decent product; the demand for inerts declined. Day-off sound like a fair trade.
